Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Dermount comes from the Irish Gaelic Mac Diarmada, which means "son of Diarmuid," or, son of Dermot and belongs to the venerable Irish tradition of patronymic
naming. However another source claims the name came from the Irish diarmaid, which meant "the god of arms." CITATION[CLOSE]

Early Origins of the O'Dermount family
The surname O'Dermount was first found in County Roscommon
(Irish: Ros Comáin) located in central Ireland
in the province of Connacht
, where the family is believed to have been descended from the Heremon
dynasty of Irish Kings and were known as the Princes of Moylurg, or the Kings of Connacht, known as the Clann Mulroona. Specifically they were descended from Teige, a King of Connacht
and his son, Murtogh, Prince of Moylurg. Their ancient territories were in the counties of Roscommon
. They were divided into three septs. One of the septs embraced English rule early and relatively painlessly, the other two suffered at the hands of Strongbow's invasion in the 12th century. Of the other two septs, the more prominent is based in Coolavin, in Sligo
. This sept was originally found at Moylurg and controlled a large part of Roscommon
. The head of this branch was one of the few leaders who is still credited as an authentic chieftain
by the Genealogical Office of Ireland
, conferring the rightful title The MacDermot. Moreover, the chief is also unofficially styled Prince of Coolavin. The third sept held a family seat
at Kilronan in the north of Roscommon
, and was referred to as MacDermot Roe, from the word ruadh, which means "red."

Migration of the O'Dermount family to the New World and Oceana
A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the O'Dermount name: Jo Dermott who settled in Virginia in the year 1635 at the age of 21; John, Thomas, James, and William Dermot settled in Philadelphia, Pennsylvania between 1774 and 1804.
The O'Dermount Motto
The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Honor probataque virtus
Motto Translation: Honour and approved valour.
